Place temporary pacemaker 3. It should be kept in mind that on occasions, beta-one agonist can result in increased ventricular ectopy e.g., in severe myocardial ischemia (by increasing myocardial demand), or sometimes with congenital long-QT syndrome. Even with tachycardia and a paced QRS duration of ~0.16 J Am Coll Cardiol.

Ivabradine is an anti-arrhythmic agent that reduces the heart rate through inhibition of the pacemaker current of the sinoatrial node. It has been used to treat both inappropriate sinus tachycardia and sinus tachycardia related to heart failure in children and adults.

An Initial ECG was performed: Initial ECG: Sinus tachycardia with prolonged QT interval (QTc of 534 ms by Bazett). She was admitted to the ICU where subsequent ECGs were performed: ECG at 12 hours QTc prolongation, resolution of T wave alternans ECG at 24 hours Sinus tachycardia with normalized QTc interval. No ischemic ST changes.

A fast heartbeat is called tachycardia, while a slow heartbeat is called bradycardia in medical terms. Hypoplastic left heart syndrome is a common congenital heart defect in which there is a problem with the heart's blood supply, and the left side of the heart does not develop correctly.

Thrombus can sometimes occur when there is a central venous catheter or a multiple pacemaker or defibrillator leads there that can cause thrombus formation. So a prominent A wave in a complex congenital heart disease situation would indicate that interventricular septum is intact. Obstruction could be due to tumour or even a thrombus.
